Abstract
The present invention provides a power on/off control architecture for a power supply so as to control the power on/off of the power supply. The power supply includes a rectifying unit, a standing power system, a PWM (Pulse Width Modulation) controller and a main power system. The standing power system controls whether the PWM controller can obtain the DC power required for operation, and in this power on/off control architecture for the power supply, a first power on/off unit is disposed in front of the DC power input port of the standing power system, so that the first power on/off unit can control the operation of the standing power system so as to further control the power on/off of the power supply.
